Embodiment Construction

[0030] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.

[0031] From the analysis of the basic principle of the electromagnetic railgun, it is equivalent to a single-turn current motor, which is a launcher that propels the armature 2 and accelerates the projectile by means of electromagnetic force. The working principle of the entire electromagnetic railgun system is as follows figure 1 shown.

[0032] The electromagnetic railgun consists of two parallel-connected high-current fixed rails and an armature 2 that maintains good electrical contact with the rails and can slide along the axis of the rails 1 . When the power supply is connected, the curr...

Abstract

The invention relates to an electromagnetic rail gun rail based on the micro conical shape, and belongs to the field of electromagnetic rail guns. The problem that in the prior art, an armature is subjected to failed contact at the tail end of the rail is solved. The rail comprises a first rail body and a second rail body; an armature of an electromagnetic rail gun moves between the first rail body and the second rail body; and the distance between the positions, close to the gun muzzle end, of the first rail body and the second rail body is smaller than the distance between the positions, away from the gun muzzle end, of the first rail body and the second rail body. In the rail gun emitting process, through the design, the effective contact area of the armature and the rail can be increased, the situation that ignition ablation and the like occur due to the fact that the armature deviates from the rear middle section of the rail is reduced, heat generated in a gun bore is decreased, and the rail is protected quite well.

Description

technical field [0001] The invention relates to the technical field of electromagnetic railguns, in particular to a microcone-based electromagnetic railgun rail. Background technique [0002] The electromagnetic railgun is composed of two high-current fixed rails connected in parallel and an armature that maintains good electrical contact with the rails and can slide along the axis of the rails. When a power source is applied, current flows through the armature along one track and back through the other, thus forming a closed circuit. When a large current flows through two parallel rails, a strong magnetic field is generated between the two rails. This magnetic field interacts with the current flowing through the armature to generate an electromagnetic force that pushes the armature and the projectile placed in front of the armature along the rails. Accelerate the movement to obtain high speed. During launch, the orbit will be subjected to electromagnetic expansion forces....
